Foam break-up under swirling flow in inlet cyclone and GLCC©

The experimental results show that foam stability increases with increasing surfactant concentration, having an exponential decay effect on foam break-up efficiency in the cyclone. For the 0.05 m inlet cyclone and GLCC, at low G, only negligible foam break-up occurs. On the other hand, at high G, higher foam break-up efficiency is achieved. Comparison of the foam break-up efficiency demonstrates a slightly better performance of the GLCC, as compared to the inlet cyclone.
